I've been using Terraco Handycoat Interior on the last two jobs and I found it brilliant. Previous purchases of this type of product has not gone so well but I've found this ready mixed skim coat brilliant. What it's good for is a thin skim. I've used on emulsion that was orange peal surface and as a spot filler which it is amazing at snagging up. To skim a wall after removing paper, a wiz with 80g mesh, I've used beeline to seal although I think it would go over gardz a treat. I never had any gardz so used beeline. Seems so versatile I've used on skirting and doorframes to smooth over woodwork as you would with fine surface filler. It's brilliant at spot filling after first coat of emulsion, as it takes out imperfections so easy. I use my filling knife to apply then 240g to sand (minimal if needed) then paint over and you can't see it. No need to prime. BM regal was covering filled spots in one coat this week. Drying is quick. For spot filling 15-30mins max especially with a fan on. For complete wall skims I smooth on and if needed I've wet sponge then another second coat in 90 minutes. I'm only using for thinly applied skims but it can says it be used over artex, but I've not tried as not sure about that. It's only good for 2mm thickness, so not good for filling holes or anything deep so artex would need to be a shallow pattern to skim. I've been using standard lightweight filler on anything deep like holes then 30 minutes later over with Terraco. Also used this for applying mesh tape to cracks and worked a treat. Just need to say this in not thick stuff. It's very sloppy but it's glass smooth application, and I've not needed to use any of my usual toupret powder. Just too easy popping lid and take a bit out vs mixing powder. You buy direct (not mobile site, go for desktop view) at £10.50 for 5kg tub (which is half full tub) with £10 delivery. I bought 4 last order (£52) and used 3 tubs to skim small bedroom walls. This is not the same product as @mistcoat 4t as that's a lightweight product while I think this is not. For bigger jobs 4t maybe better value. They were marketing terreco at the painting decorating show 2019 with demos. Definitely worth buying a couple to try imo, if only for general filling. Many here would like it for snagging and filling and taping cracks imo. No messing about mixing up, which saves time with no wastage. Going to order some 4t soon as keen to try that for interest You can watch video below. I bang on then use putz to flatten but any large blade will work. Their quoted drying times seem a bit long to me as I've two coated in a morning no problem. 180-240 mechanical sand no problem with very little dust.
